Enter information about the Failures and Assets that you want to include in the analysis. When you provide the information, consider the following:
- A minimum of three failure datapoints are needed to perform a calculation.
- If you enter downtime values that exceed the next failure date, the GE Digital APM system will highlight the downtime values on the Reliability Distribution Failure Datawindow. When you close the Reliability Distribution Failure Data window, an error message appears in the Analysis Information section.
- Days will be assumed to be the units for both downtime and operating time for the data that you enter. After you create the analysis, you can change the time units.
